CARD-FEEE.

Speciceton of Letters Potent.

Patented Mey 14, 1907.

Application filed Pein-nary 20, 3.996. Serial No. Silf Be it known thatI, JAMES WALKER Soo'rr, e citizen oi the United States, residing etGswego, in the county ol" Oswego end State of New York, have invented e.new end useful Card-Feeder, of which the following is e speciicetion.

This invention relates more particularly to that class of machinescommercially known as Brernwell feeders. In this elses of feeders,considerable difficulty hes been exerienced in providing inechenisrnthet will eed all the materiel placed therein end iced the seine evenlyto the weighing mechanism. This has led to the eniployinent oi presserplates or mechanism which will meinte-in the stock against the conveyer.While this has to e certain extent accomplished its purpose, it is foundthat the comb which controls the amount of stock carried oil` by theconveyor, when employed in connection with the presser devices, liefs etendencqfT to se erste the long end short stock and return t e letter tothe hopper or receptacle, moreover, partially stripping the conveyorteeth so ythat the saine deliver uneven quantities to the wei 7hingineohenisni. of t e conveyor delivering the stock in mixed condition, itis very ept to feed the long stock lirst and nelly the short materielthat hes been combed oil the conveyor, and inrtherrnore, the unequalfeeding is objectionable es the weighing mechanism will operate i muchbetter when e continuous equal amount is being fed thereto.

The present invention has :for its objectV the provision of novel endsini le Ineens,

whereby the materiel in its mixe condition, Y

as ceo ht by the conveyer will be evenly delivere from the feeder, andthe selection or se eration of the diiierent classes of stock, with thereturn of the shorter, is entirely avoided.

Another end importent object is to provide simple elerm and stopniechenislns, whereb)T when the stock in the feeder is low, or aboutexhausted, the operator will be notiiied, end the entire cerdingmechanism supplied by the feeder, may be automaticelly stopped ifdesired.

An embodiment of the invention that is et present considered thepreferable one is .shown in the accompanying drawings, where- 1n:-

The general structure of e well known type of feeder is disclosed, theseine comprising s receptacle preferably in the .forni oi e hopper 6.The iront well of this hopper or receptep cle consists of en upwardlyextending endless conveyor 7, having outwardly extendin teeth 8.Journeled in the upper portieri o the receptacle is e rock-shaft 9, endsecured to seid rock-shaft between the end wells 10 of the receptacle ise depending presser in the form of e plete 11 that swings with theroeksheft Q, end is movable toward end from the oonveyer. The lowerportion of the plate 11 is preferably provided on its front side withforwsrdly extending teeth l2 which teeth are thus dis osed in opposingreletion to the The presser plete is vieldinglgr urged toward theconveyer by Ineens of s weight 13, slidehlg rnoonted as shown at 1 4upon an erm 15, secured between its ends to one of the projecting endsof the rook-shaft 9, and located exteriorly of the easing Yorreceptacle. The forwardly extending portion IGof the erm is arranged toabut Yegeinst a, stop 1'? mounted on the adjacent end well 10, and thisstop is so located that the inwardly swinging movement of the presserplete 11 is limited to prevent the teeth thereof coming into contactwith the teeth of the conveyer.

Associated with the above-described niechsnisrn, is e. suitable comb. Inthe present embodiment, n. rock-shaft 18 is journaled in the end wellsl() outside of the presser plete 11, and is'provided between said endwalls with forwardly extending arms 19 secured thereto, which erinsproject through slots 20 in the presser plete sndoairry at their innerends e conib 21 of any suitable structure. This comb thus operstesbetween the presser pletel end the conveyor and between the n per endlower edges of the former. T e rock-shaft 1S is operated in any suitablemanner, es for instance, by ineens of e pitrnen 22 pivoted to e, crankerin 23, secured to one end of the shaft, the pitrnsn being IOO IIO

also connected to a pulley t driven through thc medium ol' a belt 25lirom oiuI oll tlul conveyor shal'ts, as 26.

llie operation olI the mechanism may be brielly described as liollows.The stoel( is placed in the receptacle in the ordinary manner, and whensaid receptacle .is full, the presser will be in its rcarniostpositioii,asin dirated in dotted lines. The weight 13, however, servesto yieldingly urge the plate toward the conveyor, and as the material inthe receptacle or hopper is carried away by the conveyor, the presserplate vwill swing toward said conveyor. The comb 2]V is continuallyoscillatcd between the plate and the conveyor, and is consequentlycombing oll' the surplus material from the latter. Instead ol thismaterial being returned, over or by the presser plate, back on the topof the body of stock iii the hopper, it is retained by thi` presser, sothat it will be immediately reengagcd by the teeth of the conveyer, andthus thc conveyor teeth will at all times be kept i ull and an evenquantity be carried aavay to the weighing mechanism. Experience hasdemonstratcd that as a result of this arrangement there is p actically.no selection or separation between the long and short material, andboth are maintained in their mixed con-A dition and lcd evenly to theusual weighing mechanism, whether the hopper is tilled or not.

For the purpose of notifying the operator or attendant when the stockbecomes exhausted or is low, the lollowing mechanism preferablyfciiiployed. A bell 27 is provided that may be placed in any positiondesired, and an electrical circuit shown diagrammatically at 2S includessaid bell, a source of electrical energy 2.1), and a switch or circuitcloser 30. The switch or circuit closer comprises a supporting body 31,adjustably mounted on one end of the wall 10 of the body by means of ascrew 32 that is passed through a slot 33 in the support. A pair ofspaced contact springs 34 are secured, as shown at 35 on one end portionof the body, and have their free terminals disposed contiguous to eachother, but out of contact. To these spring coiitacts 34 the wires of thecircuit 28 are connected. An actuating plunger 36 is slidably mounted onthe body, and has one end movable between and into engagement with thecontact springs, the other end of the plunger being connected to a link37 having a pivotal connection with a crank arni 38 carried by therock-shaft 9. It will thus be apparent that when the presser plate 11swings to its innermost position, the arm 38 will be swung in acorresponding direction, the plunger 36 will be forced between thecontact springs 34, and consequently the circuit will be closed, therebyringing the bell 27 and notifying the attendant or operator of thecondition of the machine. If desired suiti l l l l l l l l l l l l ableelectrically operated stop mechanism, shown diagraillniatically at 3E),may be included in the circuit 2S, and this mechanism may be so arrangedthat when the circuit is closed, the entire rarding mechanism associatcdwith the l'eeder can be stopped.` Any well known or desired type ol'stop mechanism may be employed, as desired, and it is therefore believedto be unnecessary to de* scribe the saine in detail.

From the foregoing, it is thought that the construction, operation, andmany advantages ol vthe herein described invention will Je app-arent tothose skilled in the art, without further description, and it will beunderstood that various changes in the size, shape, proportion, andininoi details of construction may be resorted to without departing fromthc spirit or sacrificing any ol the advantages ol' the invention.
